Description

Technical field:

[0001] The utility model relates to the technical field of coating production, in particular to a foam eliminating device for coating production. Background technology:

It is typically a resin, oil, or emulsion, with or without pigments, fillers, and additives, and is prepared using organic solvents or water.

[0003] During the paint processing process, the paint needs to be mixed and stirred. During the stirring process, if the stirring is uneven, a large amount of foam will appear in the paint and float on the surface of the paint, affecting the subsequent painting and causing uneven coating.

[0018] The limiting groove is formed on the inner wall of the guide groove, and the limiting groove is used to provide space for the entry of the limiting block.

[0019] By adopting the above technical solution, when the coating is stirred by the stirring rod, the height of the crushing rod can be fixed by utilizing the relative resistance generated by the stirring.

[0024] The bottom end of the limiting block is in an inclined state, and the inner cavity of the limiting groove matches the outer wall of the limiting block.

[0025] By adopting the above technical solution, the lower end of the inclined limit block can provide guidance for the automatic reset of the crushing rod when it is no longer working.

[0026] The inner side of the guide groove matches the outer wall of the breaking rod.

[0027] By adopting the above technical solution, a guide can be provided for the up and down movement of the breaker bar.

[0034] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0036] The elimination mechanism 4 includes a limiting unit and a crushing unit;

[0037] The crushing unit is used to crush bubbles on the surface of the coating;

[0038] The limiting unit is used to fix the position of the breaker rod 401;

[0039] The crushing unit includes a crushing rod 401 and a guide groove 405;

[0040] The guide groove 405 is provided on the outer wall of the stirring rod 3 and is used to provide guidance for the vertical movement of the crushing rod 401;

[0041] The breaker bar 401 is vertically slidably mounted on the inner wall of the guide groove 405 and extends to the outside of the guide groove 405;

[0042] The limiting unit includes a force block 402, a rotating rod 403, a limiting block 404, and a limiting groove 406;

[0043] The rotating rod 403 is rotatably mounted on the inner wall of the crushing rod 401, and the rotating rod 403 is used to drive the force block 402 and the limit block 404 to move;

[0044] The force block 402 is fixed to the outer wall of the rotating rod 403 and is located outside the breaking rod 401. The force block 402 is used to transmit external resistance to the rotating rod 403.

[0045] The limit block 404 is fixed to the outer wall of the rotating rod 403 and extends to the outside of the crushing rod 401. The limit block 404 is used to limit the movement of the crushing rod 401;

[0046] The limiting groove 406 is formed on the inner wall of the guide groove 405 , and is used to provide space for the limiting block 404 to enter.

[0047] In this embodiment, the stirring rod 3 is placed on the inner side of the paint bucket 1 through this structure. At this time, the crushing rod 401 on the outer surface of the stirring rod 3 will move upward along the inner side of the guide groove 405 under the buoyancy of the paint. Then, the driving motor 2 is started to drive the stirring rod 3 to rotate, and the rotating stirring rod 3 will stir the paint. During the stirring process, the force block 402 on the outer side of the crushing rod 401 rotates with the rotation of the crushing rod 401 and the stirring rod 3. The force block 402 is subjected to the reaction force from the paint and gives a thrust to the rotating rod 403 to rotate the rotating rod 403. The rotating rotating rod 403 will synchronously drive the limit block 404 on the outer wall to move, so that the limit block 404 is stuck in the inside of the limit groove 406, limiting the crushing rod 401 so that the crushing rod 401 no longer moves vertically. Therefore, under the rotation of the stirring rod 3, it always remains on the upper surface of the paint, and the bubbles and foam on the upper surface of the paint are cleared, thereby achieving the purpose of clearing the bubbles and foam on the upper surface of the paint during the stirring process and reducing the generation of bubbles.

[0048] Please refer to Figures 1 to 3 The bottom end of the breaking rod 401 is formed with a serrated groove, which is evenly distributed at the bottom end of the breaking rod 401. The inner wall of the breaking rod 401 is formed with a rotation space for the rotating rod 403 to rotate, and the outer wall of the breaking rod 401 is formed with a rotation groove for the force block 402 and the limit block 404 to rotate. The bottom end of the limit block 404 is inclined, the inner cavity of the limit groove 406 matches the outer wall of the limit block 404, and the inner side of the guide groove 405 matches the outer wall of the breaking rod 401.

[0049] In this embodiment: through this structure, when the breaker rod 401 is not subjected to the buoyancy from the paint, the force block 402 and the limit block 404 can be reset by giving the force block 402 a reverse rotational thrust, so that the breaker rod 401 drives the limit block 404 to move downward along the inner side of the limit groove 406 under the action of gravity, waiting for the next work.

[0050] Working principle: Through this structure, the stirring rod 3 is placed on the inner side of the paint bucket 1. At this time, the crushing rod 401 on the outer surface of the stirring rod 3 will move upward along the inner side of the guide groove 405 under the buoyancy of the paint. Then, the driving motor 2 is started to drive the stirring rod 3 to rotate. The rotating stirring rod 3 will stir the paint. During the stirring process, the force block 402 on the outer side of the crushing rod 401 rotates with the rotation of the crushing rod 401 and the stirring rod 3. The force block 402 receives the reaction force from the paint and gives the rotating rod 403 a thrust to rotate the rotating rod 403. The rotating rotating rod 403 will synchronously drive the limit block 404 on the outer wall to move, so that the limit block 404 is stuck in the limit The inside of the positioning groove 406 limits the breaking rod 401, so that the breaking rod 401 no longer moves vertically, so that under the rotation of the stirring rod 3, it always remains on the upper surface of the paint, and the bubbles and foam on the upper surface of the paint are cleared, thereby achieving the purpose of clearing the bubbles and foam on the upper surface of the paint during the stirring process, reducing the generation of bubbles. When the breaking rod 401 is not subjected to the buoyancy from the paint, the reverse rotation thrust is given to the force block 402 to reset the force block 402 and the limiting block 404, so that the breaking rod 401 drives the limiting block 404 to move downward along the inner side of the limiting groove 406 synchronously under the action of gravity, waiting for the next work.
